Adding a list item in editor mode does not work

I’m trying to add a list item in editor mode. I place the cursor at the end of the last link and press ‘enter’. The cursor jumps to the line below, but I don’t get a new ‘list’ item. Does anyone have an idea how to solve this? Thanks in advance.

Yep, I ran into this problem too. It doesn’t make any sense from editors’ perspective. I guess the solution would be to use rich text almost everywhere during the build so editors could edit it properly.
